Breathing Valve Mask

Breathing valve masks, also known as air valve masks or exhalation valve masks, are a type of protective face mask that is designed with a one-way valve to help improve breathability. These masks typically feature a built-in valve that allows for easier exhalation and reduces moisture and heat buildup inside the mask.

The main purpose of breathing valve is to make it easier for the wearer to breathe out, which can be especially helpful during physical activities or extended wear. This design can also help prevent the accumulation of moisture inside the mask, which can improve overall comfort and reduce the likelihood of the mask becoming damp or uncomfortable.

Features

• High efficiency and low resistance filter material, multi-stage filtration
• Filtration efficiency > 98%, low respiratory resistance, large dust capacity
• The middle layer is made of melt-blown non-woven fabric which can filter the dust in the air

• Breathing valve mask design closely fits the face, effectively prevents polluted air from entering from the edge gap, and is comfortable to wear!
